[0043] In order to enable people to notice the alarm in a noisy and dimly lit environment or in a poor vision environment, and to promptly remind people to pay attention to emergency situations and ensure life safety, a leakage warning device for electric transmission is proposed in this application. Figure 1 The structure diagram of the leakage warning device for electric transmission which is sleeved on the installed component in the embodiment of the utility model is shown in FIG. Figure 2 This is an exploded view of the leakage warning device for electric drive in the embodiment of the utility model. Figure 3 This is a schematic diagram of the structure of the odor warning mechanism, the second clamping sleeve 22, the third clamping sleeve 5 and the connecting plug 6 in the embodiment of the utility model. Figure 4 This is an enlarged view of the odor warning mechanism and the second ferrule in the embodiment of the utility model, as shown Figures 1 to 4 As shown, the leakage warning device for electric transmission may include: a shell 2, the shell 2 has an opening 24, and a housing cavity is formed in the shell 2; an acoustic and optical sensor 4, the acoustic and optical sensor 4 is used to emit an acoustic and optical alarm; an odor warning mechanism 3, part of the odor warning mechanism 3 is arranged in the housing cavity, and the odor warning mechanism 3 is electrically connected to the acoustic and optical sensor 4; the leakage warning device for electric transmission has a first state, in the first state, the acoustic and optical sensor 4 emits an acoustic and optical alarm, and at the same time, the odor warning mechanism 3 emits a preset odor.

[0044] The leakage warning device for electric drive in the present application electrically connects the odor warning mechanism 3 and the sound and light sensor 4. When the sound and light sensor 4 sends out a sound and light alarm, the odor warning mechanism 3 is also turned on synchronously to send out a preset odor. The preset odor sent out by the odor warning mechanism 3 can be dispersed through the opening 24, so that people nearby can not only receive the sound and light alarm, but also receive the alarm of the preset odor, which can greatly enhance the warning effect, and then people can notice the alarm in a noisy and visually dim environment or poor vision, which helps to remind people to pay attention to emergency situations in time and ensure life safety.

[0045] Specifically, if Figure 1 and Figure 2As shown, the housing 2 may include a first ferrule 21 and a second ferrule 22, which are installed together to form a receiving cavity. When the first ferrule 21 and the second ferrule 22 are disassembled and separated, the odor warning mechanism 3 may be installed in the receiving cavity, and after the installation is completed, the first ferrule 21 and the second ferrule 22 are connected together.

[0046] The first ferrule 21 and the second ferrule 22 may be annular, and the first ferrule 21 and the second ferrule 22 are installed together to form an annular accommodating cavity. In the above manner, the housing 2 can be conveniently sleeved and installed on the installed component 1. For example, the installed component 1 can be an electric motor.

[0047] A third clamping sleeve 5 made of rubber is arranged on the inner side wall of the second clamping sleeve 22, and the third clamping sleeve 5 is used to increase friction, so that when the housing 2 is sleeved on the installed component 1, it can prevent the leakage warning device for electric transmission from easily falling off from the installed component 1.

[0048] The acoustic and optical sensor 4 can be fixedly connected to the housing 2. The acoustic and optical sensor 4 is generally connected to the outside of the housing 2, so that the acoustic and optical signals emitted by the acoustic and optical sensor 4 can remind relevant personnel.

[0049] The preset odor emitted by the odor warning mechanism 3 can be a pungent odor, which can enhance the warning effect and facilitate the relevant personnel to find. In order to increase the total amount of the preset odor emitted by the odor warning mechanism 3, there can be multiple odor warning mechanisms 3, and the multiple odor warning mechanisms 3 are distributed in the accommodating cavity along the circumferential direction.

[0050] As feasible, Figure 5 FIG. 1 is a schematic diagram of the structure of the odor warning mechanism in the embodiment of the utility model. Figure 4 and Figure 5 As shown, the odor warning mechanism 3 may include: a first reaction component 31; a second reaction component 32 spaced apart from the first reaction component 31, and when the second reaction component 32 contacts the first reaction component 31, a preset odor is generated; and a driving mechanism 33. The driving mechanism 33 can drive the second reaction component 32 to move along a first preset direction toward the first reaction component 31 so that the two contact each other.

[0051] When the odor warning mechanism 3 does not need to emit a preset odor, the first reaction component 31 and the second reaction component 32 maintain a distance between them, and the second reaction component 32 and the first reaction component 31 do not react to produce a preset odor. When the odor warning mechanism 3 needs to emit a preset odor, the driving mechanism 33 drives the second reaction component 32 to move toward the first reaction component 31 so that the two contact, so that the second reaction component 32 and the first reaction component 31 react to produce a preset odor.

[0052] As a feasible method, one of the second reaction component 32 and the first reaction component 31 may include sulfur. Sulfur is a single substance of the non-metallic element sulfur. Sulfur usually exists in the form of ore and is also a gas produced during volcanic eruptions. Sulfur has a pungent smell, active chemical properties, and can react with other elements and compounds. The second reaction component 32 and the other one of the first reaction component 31 may include potassium nitrate. Potassium nitrate is a colorless transparent crystal belonging to the nitrate compound. It is a chemical substance widely used in agriculture and chemical industry. Less sulfur and potassium nitrate contact to produce a preset gas, which is mainly a small amount of pungent sulfur dioxide, which can be used to remind others. The second reaction component 32 and the first reaction component 31 may respectively include a support plate, and the sulfur or potassium nitrate is arranged on the support plate.

[0053] As a feasible method, part of the odor warning mechanism 3 may pass through the opening 24, so that the preset odor emitted by the odor warning mechanism 3 is easier to diffuse.

[0054] like Figures 1 to 5 As shown, the odor warning mechanism 3 may include: a shield 34, the shield 34 has a hollow structure 341, the first reaction component 31 is arranged in the shield 34, and at least part of the shield 34 is arranged outside the housing 2. On the one hand, the shield 34 can contain the first reaction component 31, and on the other hand, when the second reaction component 32 reacts with the first reaction component 31 to produce a preset odor, the odor in the shield 34 can be quickly dissipated through the hollow structure 341. The shield 34 can be installed outside the housing 2, and its installation position corresponds to the opening 24 on the housing 2. The shield 34 can be directly connected to the housing 2.

[0055] In order to prevent the leakage warning device for electric transmission from causing erroneous reaction due to the second reaction component 32 and the first reaction component 31 contacting after a collision, as shown in FIG. Figure 4 and Figure 5 As shown, the odor warning mechanism 3 may include: a stopper 35 having a sliding portion 351, the sliding portion 351 extending along a first preset direction, and the second reaction component 32 having a stopper 321, the stopper 321 being arranged in the sliding portion 351, so that the driving mechanism 33 can drive the second reaction component 32 to move along the first preset direction. Due to the existence of the stopper 35, the second reaction component 32 can only move along the sliding portion 351 in the first preset direction, and when sulfur and potassium nitrate are respectively arranged on the sides of the support plate facing each other, the above method can ensure that one side of the support plate with sulfur is in contact with one side of the support plate with potassium nitrate, thereby ensuring a controllable reaction between sulfur and potassium nitrate.

[0056] Furthermore, there may be two limiters 35, which are arranged opposite to each other, and the second reaction component 32 has two limiters 321, which are respectively arranged in the two sliding parts 351. The above structure can effectively ensure the stability of limiting the second reaction component 32.

[0057] In order to enable the driving mechanism 33 to drive the second reaction component 32 to move along the first preset direction, it is feasible as follows: Figure 4 and Figure 5 As shown, the driving mechanism 33 may include: a motor 331 and a fan 332 connected to the motor 331, and the fan 332 faces the side of the second reaction component 32 that is opposite to the first reaction component 31. When the motor 331 drives the fan 332 to rotate, the wind blown by the fan 332 can blow the second reaction component 32 to move in the direction of the first reaction component 31, and finally cause the second reaction component 32 to react with the first reaction component 31 to produce a preset smell. After the preset smell is produced, the wind blown by the fan 332 can cause the preset smell to diffuse quickly and overflow from the shield 34 to the outside of the housing 2.

[0058] like Figures 1 to 3 As shown, the second ferrule 22 may be fixedly connected with an annular connecting plug 6 for inserting into the accommodating cavity of the first ferrule 21. In order to fix the motor 331, the motor 331 may be fixed on the connecting plug 6, and the motor 331 may also be fixedly arranged on the first ferrule 21.

[0059] The second ferrule 22 may have a mounting groove 221 inside, the position of the mounting groove 221 corresponds to the opening 24 on the housing 2, and the stopper 35 and the second reaction assembly 32 may be arranged in the mounting groove 221. The function of the mounting groove 221 is to gather the airflow generated by the fan 332 therein, so that the gathered airflow pushes the support plate of the second reaction assembly 32 to move. The stopper 35 may be fixedly connected to the mounting groove 221.

[0060] When the motor 331 is not rotating, in order to ensure that the second reaction component 32 does not move toward the first reaction component 31, Figure 5 As shown, the fan 332 is connected to the second reaction component 32 through the anti-collision strip 36. The anti-collision strip 36 can fix and control the position of the second reaction component 32. When the fan 332 rotates, the limit portion 321 of the second reaction component 32 is disconnected under the action of the circumferential limit of the sliding portion 351, and then the second reaction component 32 can move toward the first reaction component 31. Further, there can be multiple anti-collision strips 36, and when the fan 332 is in a stationary state, the anti-collision strips 36 can connect the fan 332 to the support plate of the second reaction component 32.

[0061] As feasible, Figure 1 and Figure 2 As shown, the outer wall of the housing 2 has a plurality of strip grooves 23 distributed in a circumference. For example, the outer walls of the first ferrule 21 and the second ferrule 22 each have a plurality of strip grooves 23 distributed in a circumference. The strip grooves 23 can increase the friction coefficient between the first ferrule 21 and the second ferrule 22 and the hand, and the friction coefficient is an indicator of the friction between two objects. The larger the friction coefficient, the better the anti-slip effect.
